EDGE-SETTING MACHINE.

To all whom it may concern 7 Be it known that I, VINCENZO FRANOnINO, asubject of the Kingof Italv. and aresident 1 of Orange, in the county ofEssex and State of New Jersey, have mvented certain Im-- provements inEdge Setting Machines, of which the following is a specification.

This invention relates to that class of shoe making machines which areused to round off the lower peripheral edge of the sole of a shoe andhas for its objects to provide an improved machine of this character; toad mit regulating the machine without stop ping the same; tothus adaptthe machine to use with a sole of any thickness; to -indicate thethickness of sole for whichthe machine is set; to provide resilientmeans for pressing the. movable sleeve toward the head; to

secure simplicity of construction and operation, and to obtain otheradvantages and results as may be brought outin the followingdescription.

Referring to the accompanying drawings,

in which like numerals of reference indicate the same parts throughoutthe several views, Figure 1 is a front elevation. of a machine embodyingmv invention; Fig. 2 is a longitudinal vertical section of the same;Fig. 3 is a plan view,.and Fig. 4 is a cross-sectional view on line A-Aof Fig. 2.

In'the specific embodiment of the invention illustrated in saiddrawings, the reference numeral 1 indicates a rotatable spindlepreferably mountedhorizontally'in a suitable base 2. A driving pulley 3is secured to the spindle as by av set screw 4 and prevents the spindlefrom shifting longitudinally by engagement with bearing portions 5, 5 ofthe base, although it will be'under-.

stood that any suitable or equivalent means could be employed. At oneend th1s spindle is enlarged and forms a head 6 providing an annularshoulder 7 facing toward the opposite end of the spindle. Slidablymounted upon the spindle between said shoulder and the adjacent bearing5, is a rasping or burnishing sleeve 8 suitably roughened on its endtoward the shoulder so as tomore readily round off and burnish the edgeof. the sole when brought into engagement-therewith. The rasping orburnishing sleeve 8 is keyed onto the spindle manner so as to beslidably but'non-rotatably mounted thereon, and to this end are shown aplurality of keys or splines 9 in the central aperture of the sleevewhich en- Specification of Letters Patent.

gag e within corresponding slots or keyways 10 cut for conveniencein acollar 11 secured V to'the spindle adjacent the head. Obviously,therefore,-the movable sleeve 8 maybe slid back and forth upon thespindle at will but will be rotated therewith. It 'maybe here notedthatthe end of the keys 9 projectbeyond the end of the sleeve 8 towardthe shoulder 7 a distance substantially equal to the smallest thickness]of shoe sole to be edged. Furthermore the radially outer face of saidkeys have the longitudinal edges rounded off and the adjacent outeredges of the slots are also rounded so as to provide a roughened surfacefor edging the shoe sole; Preferably the metal between the slots is cutaway at the periphery of the ring to a suitable depth at a distance fromthe shoulder 7 this distance when added to the distance the keys 9project beyond the sleeve 8 being equal to the greatest thickness ofsole to be treated. I I

Preferably between the rasping or burnishing sleeve and the adjacentbearing'5 around the spindle is inserted a helical spring 12 which bearsagainst the sleeve and bearing and tends to normally slide the sleevetowardthe shoulder '7. Obviously the sole of a shoe may be inserted atits edge between the shoulder T and the sleeve with its bottom facingthe sleeve and with the spindle rotating and the spring pressing thesleeve against the sole, frictional wearing and burnishing of the edgewill be per-' formed to round off the same as desired. Furthermore thesleeve in shifting to accommodate various thicknesses of sole will presswith less force against the thinner, and with greater force against theheavier soles to give a less or greater'rounding of the edge.

Under some conditions it is desirable to maintain the sleeve in positionto operate upon soles of some particular thickness. With this purpose inview I cut a peripheral groove 13 in the exterior of the rasping orburnishing sleeve and mount thereabove' an arm 14 having its lower endforked and riding in said groove; The upper end of said arm is providedwith a' transversesleeve 15 slidably supported by a, stationary stud 16fixed above and parallel to the spindle 1 in an extension 17 projectingupwardly from the base. Thus mounted, the arm 14: will slidetransversely of itself and parallelto the spindle In order to soslidethe arm 14,-

and will slide the sleeve 8 at the a screw or threaded member 18 issecured thereto and projects parallel to the spindle through theextension 17 to which the stud 16 is fixed. Said extension is recessedas at 19 transverse to the screw and in this recess is held a thumb nut20 upon the screw. By turning said nut, the screw will be movedlongitudinally one way or the other, since the screw isprevented fromturning and the nut is prevented from movement longitudinally of thescrew by engagement with the walls of its recess 19. In this manner, therasping or burnishing sleeve 8 may be slid and held in any positiondesired so as to operate upon any thickness of sole and this adjustmentmay be made very readily and quickly without stopping the machine orcausing any long delays in the operation thereof. Obviously the spring12 between the sleeve 8 and bearing 5, although advantageous anddesirable for positively taking up the lost motion or play always in thesame direction, may be omitted if desired when the above describedadjusting means are employed.

In order to admit setting the machine readily to the proper thickness ofsole, an

\ indicator is provided comprising a swinging hand 21 pivotally mountedin front of a scale plate 22 having appropriate designations 23 of thesize for which the machine is set. The lower end of the hand 21 isprovided with an arcuate series of teeth 24 in mesh with the teeth of arack 25 which is fixed with respect to the sleeve 15 and armlt wherebymovement of the arm in shifting the sleeve will result in acorresponding movement of the. rack. Movement of the rack, however, Willswing the hand 21 which multiplies the movement in registering upon thescale 23. It is not to be understood, however, that I limit myself tothis or any other detail construction except as specifically pointed outin the appended claims when construed in the light of the prior art.

Having thus described the invention what I claim is,

1. In a machine of the character described, the combination with arotatable spindle having a shoulder at one end, of a sleeve slidable onsaid spindle toward and away from said shoulder, said sleeve beingnon-rotatably mounted on said spindle and having a peripheral groove, astud parallel to said spindle, an arm in said groove slidably mounted onsaid stud, a threaded member secured to said arm between the spindle andthe stud, and a nut rotatable on said threaded member and arranged byits rotation to slide said sleeve back and forth on said spindle.

2. In a machine of the character described, the combination with arotatable spindle having at one end a shoulder, of a rasping orburnishing sleeve slidably mount ed on said spindle and having aperipheral groove, a stud parallel to said spindle, an arm slidable onsaid stud and having an end positioned in said groove, means for movingand holding said arm to move and hold said sleeve in any desiredposition, and means connected with said arm for indicating the positionto which said sleeve is held.

3. In a machine of the character described, the combination with arotatable spindle having at one end a shoulder, of a rasping orburnishing sleeve slidably mounted on said spindle and having aperipheral groove, a stud parallel to said spindle, an arm slidable onsaid stud and having an end positioned in said groove, means for movingand holding said arm to move and hold said sleeve in any desiredposition, said arm having a rack, and a hand having teeth engaging saidrack and adapted to be swung thereby as the sleeve is moved forindicating the position of said sleeve.

4. In a machine of the character described, the combination with a basehaving an extension, of a rotatable spindle journaled in said base, arasping or burnishing sleeve slidable on said spindle and adapted to berotated therewith and having a peripheral groove, a stud projecting fromsaid extension parallel to the spindle, an arm slidable on said stud andhaving an end portion positioned in said groove, means for sliding saidarm on said stud and there by shifting the sleeve to any desiredposition, a scale plate on said extension, a hand pivoted to swing infront of said scale plate, and means for swinging said hand as thesleeve is slid to any desired position.

5. In a machine of the character described, the combination with a basehaving aslotted extension, of a rotatable spindle journaled in saidbase, a rasping or burnishing sleeve slidable on said spindle andadapted to be rotated therewith and having a peripheral groove, a studprojecting from said extension parallel to the spindle, an armtransverse to said stud and spindle and slidable on said stud and havingan end portion positioned in said groove, a threaded member secured tosaid arm and projecting through said extension parallel to said spindle,and a nut on said threaded member within the slot of theextension formoving and holding said threaded member to move and hold said sleeve inany desired position.
